It's well documented that some women suffer depression after having a baby. But it's less well-known just how many do.
The largest study to date shows that as many as 1 in every 7 women suffers postpartum depression. And the study, published in the journal JAMA Psychiatry, finds that among women followed for a year after delivery, some 22 percent had been depressed.
The study also recommends that all pregnant women and new mothers be screened for depression.
